First-term Rep. Alexandria Ocasio-Cortez said Friday climate change is a result of “market failure.”

The New York Democrat aimed to rebut critics that her proposed “Green New Deal” is a step towards socialism. Ocasio-Cortez, who ousted an establishment Democratic incumbent in the 2018 primary, said it’s the government’s responsibility to fix the climate change issue because the capitalist market economy has proven incapable of providing solutions.
